Patent number: 8138277Abstract: Disclosed are silane-modified urea derivatives which can be produced by reacting diisocyanates with aminosilanes, hydroxysilanes, or mercaptosilanes. The inventive silane-modified urea derivatives are suitable especially for use as auxiliary rheological agents, preferably as thixotropic agents for silane-crosslinking systems, particularly for single-component and two-component adhesives and sealants, paint, lacquers, and coating while causing substantially no increase in viscosity, not being subject to discoloring, being reactive, and positively influencing mechanics.Type: GrantFiled: June 6, 2006Date of Patent: March 20, 2012Assignee: Construction Research & Technology GmbHInventors: Tobias Austermann, Michael Duetsch, Marc Laurent, Helmut Mack, Michael Porsch, Konrad Wernthaler

Patent number: 6908955Abstract: A composition that is a reaction product of two or three moieties. The first moiety (A) is a nonpolymeric, multi-functional moiety or combination of mono- or multifunctional moieties that adsorbs onto a cementitious particle. The second required moiety (C) is a linear or branched water soluble, nonionic polymer that is capable of providing dispersing capability. A third moiety (B), if present, is a nonpolymeric moiety disposed between the first and second moiety, to connect the first and second moieties.Type: GrantFiled: November 8, 2002Date of Patent: June 21, 2005Assignee: Construction Research & Technology GmbHInventors: Michael Porsch, Thomas M.
